A culture doesn't require that people meet up and agree on some way of doing things. Hence a counterculture does not need to be organized or even acknowledged while in process. It just happens and then gets written about a decade later.
I stopped taking pictures on vacation (and other events) quite a while ago because I realized I never look at them later. So I spend the time being more focused on the actual thing, and have better memories. I wouldn't like the memory erased thing.
Does "memory" include fundamental changes to the self and perception along with personal growth due to exposure to new experiences and situations and time away from the grind?
